Symptom: All tasks end in errors when using the stock v6.10 'cuda_fermi' application.

Solution/workround:
a) Use an optimised Cuda application, where available.
b) Downgrade to the 301.42 driver - only possible on GTX 670/680/690 cards, not on newer releases like the 650/660 or their Ti variants.
c) Set an environment variable, as shown below.

The environment variable to use is

CUDA_GRID_SIZE_COMPAT

and it needs to have the value 1 (one)

You need to be running in Administrator mode, and you need to be running at least driver 306.02 (BETA) or 306.23 (WHQL)
